Definitions
- the invention relates to a home consumption keg for liquid food and in particular for beer with a barrel body and a built-in wall fitting for filling, cleaning and / or emptying the keg and a Bavarian puncture in the region of the particular cylindrical circumference of the keg for tapping the liquid Food from the keg, which is connected to the Bavarian tapestry a riser.
- a home consumption keg for liquid food and in particular for beer with a barrel body and a built-in wall fitting for filling, cleaning and / or emptying the keg and a Bavarian puncture in the region of the particular cylindrical circumference of the keg for tapping the liquid Food from the keg, which is connected to the Bavarian tapestry a riser.
- a keg is known from GB 847 351 A.
- the Bavarian puncture is understood to mean a closure element which is arranged laterally in the barrel body and which is provided so that a manual tap is hammered into this cylindrical closure element, the closure element thereby opens, and then the tap itself is responsible for opening or closing the barrel body.
- Home Consumption Keg means in particular beer kegs for household use with long-term repeated Zapfrischentician without quality loss of the drink.
- Keggy which has an integrated CO 2 tank filled with liquid carbon dioxide.
- the Keggy requires a special tap head, which is structurally complex and very expensive in trade. In addition, it requires a considerable technical effort when refilling the CO 2 tank with liquid carbon dioxide.
- party kegs which consist of a five-liter tin can and thus are very small.
- the party keg can not be closed again and fills with the tap with air, which leaves a long time in the barrel remaining beverage, especially beer, quickly become shabby, because on the one hand the carbon dioxide from the beer in the air-filled interior of the party On the other hand, the oxygen diffuses from the air into the beer.
- the present invention has for its object to further develop the Home Consumption Keg described above and to improve it even further, to provide a barrel for household use, which has improved consumption characteristics.
- the fitting is arranged in the lower drum body region on the pin on the side opposite the reducing and / or non-return valve.
- the position of the fitting when tapping is not important in itself, since it is no longer needed.
- it should be at the bottom of the drum body to facilitate access to the drum interior and allow the use of a standard keg cleaning and filling machine.
- the riser has the advantage to provide a long throttle path between barrel interior and tap available, resulting in - for example, at an inner diameter of the riser of about 2 mm - a large flow resistance, thereby resulting in a low Reynolds number and ultimately a laminar flow so that the beer can be tapped with appropriate foaming.
- the known Home Consumption Kegs usually lack a corresponding technique and the pin is therefore often associated with excessive foaming in house use
- the riser ensures that even using the well-known and very simple tapping by means of a tap, the Zapfcharacter good. The reason for this lies in the flow conditions within the riser, whereby it is of course an advantage to make the riser as long as possible before the Bavarian puncture.
- the Bavarian puncture spaced from the lower end of the barrel body (or from the Gearventiltechnik arranged there) and in particular in the upper half of the barrel body (the actual barrel bottom in the later described in more detail preferred embodiment), so that the riser up into the barrel bottom opposite head region can extend over a considerable height, which leads to a further increase in the flow resistance.
- a special side effect of this upwardly laid Bavarian puncture is that it is now possible for the first time to put a beer glass under the tap, which is located on the same level as the keg. So it does not have a special special equipment for parking the glasses be arranged below the barrel, as there is sufficient space under the tap for a glass to be filled and more glasses can then be arranged in a simple manner next to this glass on the tapping table.
- the riser should preferably have a substantially increasing course to improve the flow conditions and the cleaning.
- the keg has an integrated reducing and / or non-return valve for connecting a CO 2 tank, this valve is preferably set or preset so that it has an internal pressure of 0.8 to 1.2 bar inside the barrel guaranteed.
- An external CO can be connected to the valve 2 container then be connected, or - and this is a further feature essential to the invention - the keg has an integrated CO 2 container for containing a sufficient amount of CO 2 for the complete emptying of the keg.
- the user of the keg actually needs nothing more than a simple tap to tap in the simplest way a beer that corresponds to the professional conditions, which neither has excessive foaming, nor scarf after shorter or longer periods, because the necessary pressure to tap or fill the cavity forming inside the cavity by CO 2 , which is stored in the integrated into the keg CO 2 tank.
- contamination of the beverage by ambient air is avoided and the kegs remain moist and clean inside.
- the CO 2 in the CO 2 container is gaseous.
- the filling of the once-used keg with CO 2 is much easier than if this would be in the liquid state, because then would have to be controlled by a costly volume measurement, the capacity of the CO 2 .
- Liquid becomes CO 2, for example, at 20 bar only from -10 ° C, so that the volume to be filled must be calculated taking into account the weight in consideration of pressure and temperature.
- CO 2 present in the gaseous state it is easily possible to fill the CO 2 tank until a pressure equalization with the CO 2 of the feed line exists, wherein the CO 2 tank is filled with up to 60 bar can.
- the reducing and / or non-return valve is arranged on the journal in the upper barrel body region, this has the further effect that the CO 2 is supplied to where it is needed, namely above the liquid level. So it must not first flow through the liquid, so in particular the beer at a feed from below and possibly cause foaming, but instead simply fills the upper area of the barrel inside, in which there is no more drink (beer).
- the integrated CO 2 container in the journal upper portion of the barrel, wherein expediently the integrated CO 2 container is surrounded by an upper collar ring or a sheath and protected from the environment.
- the riser runs laterally next to the fitting in the bottom area of the barrel body, wherein the "bottom area” is based on the state when tapping, so represents the side with the fitting. That is, due to the riser extending in the direction of the fitting, it will not be possible to use the barrel in the orientation of the spigot in which the fitting is at the top, since the riser would be up to the barrel top in the barrel interior and its end soon above the liquid level would be.
- the Home Consumption Keg 1 shown in Figure 1 consists of a two-deep-drawn shells barrel body 2, which are welded together at a weld 3.
- the keg has a known per se fitting 4 with connected filling pipe 18 in the upper region shown in Figure 1, but which forms the bottom portion of the keg during the pin. That is, Figure 1 shows the state for transporting the keg, while for filling and tapping the keg 1 "must be turned upside down", so that then the fitting is located in the bottom area.
- a check valve 5 is provided, through which the stored in a CO 2 container 6 gaseous CO 2 can flow after reducing pressure in a reducing valve in the barrel interior.
- the CO 2 container 6 is shown in Figure 2 in plan view even better: There is also at one end of the C-shaped bent CO 2 tank the fixed preset reducing valve 7 and on the other side of the CO 2 tank a connecting pipe 8, which connects the CO 2 tank via a pressure measuring knob 9 with a central unit 10 and finally with a high pressure valve 11 for filling the CO 2 tank.
- the barrel body has an upper collar ring 13 and a lower collar ring 14, which give the keg a secure footing or make it stackable and also protect the CO 2 fitting and the fitting against external influences.
- the collar ring 14 shown in Figure 1 below is the pin of the upper collar ring, while the collar ring 13, which is shown in Figure 1 above, when pin is the lower collar ring.
- the collar ring 14 thus surrounds the CO 2 container and protects it against external influences.
- a Bavarian puncture 15 is provided, which is integrated into the cylindrical peripheral wall of the barrel body and extending from this radially inward extends.
- a riser is provided, which extends, starting from the radial extent in the axial direction bent to the bottom portion of the barrel.
- the riser 16 is arranged at a distance from the axial axis of the barrel so that it leaves free the area of the fitting 4, thereby not hindering in particular the cleaning of the barrel interior by the opening 17 of the barrel which is filled with itself by the fitting.
- the riser has an inner diameter of only about 2 mm, to cause the greatest possible flow resistance and thereby produce a laminar flow of the beer, which leads to extremely low foam development even when using simple taps.

Description
Die Erfindung betrifft ein Home Consumption Keg für flüssige Lebensmittel und insbesondere für Bier mit einem Fasskörper und einem in dessen Wandung integrierten Fitting zum Befüllen, Reinigen und/oder Entleeren des Kegs sowie einem bayerischen Anstich im Bereich des insbesondere zylindrischen Umfangs des Kegs zum Zapfen des flüssigen Lebensmittels aus dem Keg, wobei an den bayerischen Anstich ein Steigrohr angeschlossen ist. Ein derartiges Keg ist aus GB 847 351 A bekannt.The invention relates to a home consumption keg for liquid food and in particular for beer with a barrel body and a built-in wall fitting for filling, cleaning and / or emptying the keg and a Bavarian puncture in the region of the particular cylindrical circumference of the keg for tapping the liquid Food from the keg, which is connected to the Bavarian tapestry a riser. Such a keg is known from GB 847 351 A.
Unter Bayerischer Anstich wird ein seitlich im Fasskörper angeordnetes Verschlusselement verstanden, das dazu vorgesehen ist, dass ein Handzapfhahn in dieses zylinderförmige Verschlusselement eingeschlagen wird, das Verschlusselement hierbei öffnet und anschließend der Zapfhahn selbst für das Öffnen bzw. Schließen des Fasskörpers verantwortlich ist.The Bavarian puncture is understood to mean a closure element which is arranged laterally in the barrel body and which is provided so that a manual tap is hammered into this cylindrical closure element, the closure element thereby opens, and then the tap itself is responsible for opening or closing the barrel body.
Der Begriff Home Consumption Keg meint insbesondere Bierfässer für den Hausgebrauch mit längerfristiger wiederholter Zapfbereitschaft ohne Qualitätseinbußen am Getränk.The term Home Consumption Keg means in particular beer kegs for household use with long-term repeated Zapfbereitschaft without quality loss of the drink.
Eine bekannte Variante ist das sogenannte Keggy, das einen integrierten CO2-Tank hat, der mit flüssiger Kohlensäure gefüllt ist. Das Keggy macht einen speziellen Zapfkopf erforderlich, der konstruktiv aufwendig und im Handel sehr teuer ist. Außerdem erfordert es einen erheblichen technischen Aufwand beim Wiederbefüllen des CO2-Tanks mit flüssiger Kohlensäure.One known variant is the so-called Keggy, which has an integrated CO 2 tank filled with liquid carbon dioxide. The Keggy requires a special tap head, which is structurally complex and very expensive in trade. In addition, it requires a considerable technical effort when refilling the CO 2 tank with liquid carbon dioxide.
Eine weitere Variante besteht in Party-Fässchen, die aus einer fünf Liter fassenden Blechdose bestehen und somit sehr klein ausfallen. Das Party-Fässchen kann nicht wieder verschlossen werden und füllt sich beim Zapfen mit Luft, was ein über längere Zeit im Fass verbleibende Getränk, insbesondere Bier, schnell schal werden lässt, da einerseits die Kohlensäure aus dem Bier in den mit Luft gefüllten Innenraum des Party-Fässchens diffundiert und andererseits der Sauerstoff aus der Luft in das Bier diffundiert.Another variant consists in party kegs, which consist of a five-liter tin can and thus are very small. The party keg can not be closed again and fills with the tap with air, which leaves a long time in the barrel remaining beverage, especially beer, quickly become shabby, because on the one hand the carbon dioxide from the beer in the air-filled interior of the party On the other hand, the oxygen diffuses from the air into the beer.
Als weitere Variante gibt es ein Party-Fass mit bayerischem Anstich, der wie bei den altbekannten Holzfässern im Umfangsbereich nahe des Bodens des Fasses angeordnet ist. Bei dem Party-Fass wird entweder Luft über die Füll- und Reinigungsventiltechnik in das Fass gelassen, was aber wieder zu dem beschriebenen sensorischen Problem nach längeren Standzeiten führt, oder es wird Kohlensäure aus einer externen Gasflasche über einen speziellen Zapfkopf und ein externes Reduzierventil zugeführt; die Handhabung externer CO2-Versorgungsquellen ist jedoch umständlich, nicht ungefährlich und erfordert Fachkenntnisse.As another variant, there is a party barrel with Bavarian puncture, which is arranged as in the well-known wooden barrels in the peripheral area near the bottom of the barrel. In the party keg, either air is let into the keg via the filling and cleaning valve technology, but this again leads to the described sensory problem after a longer service life, or carbon dioxide is supplied from an external gas cylinder via a special tap head and an external reducing valve; However, the handling of external sources of CO 2 supply is cumbersome, not dangerous and requires expertise.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das eingangs beschriebene Home Consumption Keg weiterzubilden und es noch weiter zu verbessern, um ein Fass für den Hausgebrauch zur Verfügung zu stellen, das verbesserte Verbrauchseigenschaften aufweist.The present invention has for its object to further develop the Home Consumption Keg described above and to improve it even further, to provide a barrel for household use, which has improved consumption characteristics.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Fitting im bein Zapfen unteren Fasskörperbereich angeordnet ist.This object is achieved in that the fitting is arranged in leg journal lower barrel body area.
Gemäß der Erfindung ist hingegen das Fitting im beim Zapfen unteren Fasskörperbereich angeordnet auf der dem Reduzier- und/oder Rückschlagventil gegenüberliegenden Seite. Die Position des Fittings beim Zapfen ist an sich unwichtig, da es dabei nicht mehr benötigt wird. Beim Befüllen des Kegs sollte es sich jedoch wie beim Standardkeg an der unteren Seite des Fasskörpers befinden, um den Zugang zum Fassinneren zu vereinfachen und die Nutzung einer üblichen Kegreinigungs- und -füllmaschine zu ermöglichen. Diese an sich gegensätzlichen Anforderungen des beim Zapfen im oberen Fassbereichs anzuordnenden Reduzier- und/oder Rückschlagventils (CO2-Zuspeisung) und des beim Befüllen ebenfalls im oberen Fassbereich anzuordnenden Fittings kann man in einfacher Weise dadurch erfüllen, dass das Keg nicht nur beim Befüllen "auf dem Kopf steht", sondern beim Zapfen ebenfalls, so dass sich das Reduzier- und/oder Rückschlagventil dann am oberen Ende des Kegs befindet, während das Fitting im Bodenbereich angeordnet ist. Es sei noch erwähnt, dass das insbesondere zentrische Anordnen des Reduzierventils auf der dem Fitting gegenüberliegenden Seite auch dazu ausgenutzt werden kann, dass das Reduzier- und/oder Rückschlagventil beim Reinigen des Fassinneren mitgereinigt wird.In contrast, according to the invention, the fitting is arranged in the lower drum body region on the pin on the side opposite the reducing and / or non-return valve. The position of the fitting when tapping is not important in itself, since it is no longer needed. When filling the keg, however, as with the standard keg, it should be at the bottom of the drum body to facilitate access to the drum interior and allow the use of a standard keg cleaning and filling machine. These opposing requirements of the valve in the upper Fassbereichs to be arranged reducing and / or check valve (CO 2 feed) and to be arranged during filling also in the upper barrel area fittings can be achieved in a simple manner that the keg not only when filling " but also when tapping, so that the reducing and / or check valve is then at the upper end of the keg, while the fitting is arranged in the bottom area. It should be mentioned that the particular centric arrangement of the reducing valve on the opposite side of the fitting can also be exploited to the fact that the reducing and / or non-return valve is cleaned during cleaning of the barrel interior.
Das Steigrohr besitzt den Vorteil, einen langen Drosselweg zwischen Fass-Innenraum und Zapfhahn zur Verfügung zu stellen, wodurch sich - beispielsweise bei einem Innendurchmesser des Steigrohrs von ca. 2 mm - ein großer Strömungswiderstand, hierdurch eine niedrige Reynoldszahl und im Endeffekt eine laminare Strömung ergibt, so dass das Bier mit angemessener Schaumentwicklung gezapft werden kann. Während den bekannten Home Consumption Kegs meist eine entsprechende Technik fehlt und das Zapfen im Hausgebrauch deshalb oft mit einer zu großen Schaumentwicklung einhergeht, sorgt das Steigrohr dafür, dass selbst unter Verwendung der altbekannten und sehr einfachen Zapftechnik mittels eines Zapfhahns das Zapfergebnis gut ausfällt. Die Ursache dafür liegt in den Strömungsverhältnissen innerhalb des Steigrohrs, wobei es natürlich von Vorteil ist, das Steigrohr vor dem bayerischen Anstich möglichst lang auszuführen.The riser has the advantage to provide a long throttle path between barrel interior and tap available, resulting in - for example, at an inner diameter of the riser of about 2 mm - a large flow resistance, thereby resulting in a low Reynolds number and ultimately a laminar flow so that the beer can be tapped with appropriate foaming. While the known Home Consumption Kegs usually lack a corresponding technique and the pin is therefore often associated with excessive foaming in house use, the riser ensures that even using the well-known and very simple tapping by means of a tap, the Zapfergebnis good. The reason for this lies in the flow conditions within the riser, whereby it is of course an advantage to make the riser as long as possible before the Bavarian puncture.
Deshalb ist es zweckmäßig, den bayerischen Anstich beabstandet vom beim Zapfen unteren Ende des Fasskörpers (bzw. von der dort angeordneten Füllventiltechnik) anzuordnen und insbesondere in der beim Zapfen oberen Hälfte des Fasskörpers (dem eigentlichen Fassboden bei dem später genauer beschriebenen bevorzugten Ausführungsbeispiel), so dass sich das Steigrohr bis in den dem Fassboden gegenüberliegenden Kopfbereich über eine beträchtliche Höhe erstrecken kann, was zu einer weiteren Erhöhung des Strömungswiderstandes führt. Ein besonderer Nebeneffekt dieses nach oben verlegten bayerischen Anstiches besteht darin, dass es nun erstmals auch möglich ist, unter den Zapfhahn ein Bierglas zu stellen, das sich auf der gleichen Ebene befindet wie das Fass. Es muss also nicht extra eine Sondereinrichtung zum Abstellen der Gläser unterhalb des Fasses angeordnet werden, da ausreichend Platz unter dem Zapfhahn für ein zu befüllendes Glas bleibt und weitere Gläser dann in einfacher Weise neben diesem Glas auf dem Zapftisch angeordnet werden können.Therefore, it is expedient to arrange the Bavarian puncture spaced from the lower end of the barrel body (or from the Füllventiltechnik arranged there) and in particular in the upper half of the barrel body (the actual barrel bottom in the later described in more detail preferred embodiment), so that the riser up into the barrel bottom opposite head region can extend over a considerable height, which leads to a further increase in the flow resistance. A special side effect of this upwardly laid Bavarian puncture is that it is now possible for the first time to put a beer glass under the tap, which is located on the same level as the keg. So it does not have a special special equipment for parking the glasses be arranged below the barrel, as there is sufficient space under the tap for a glass to be filled and more glasses can then be arranged in a simple manner next to this glass on the tapping table.
Es sei noch erwähnt, dass das Steigrohr zur Verbesserung der Strömungsverhältnisse und der Reinigung vorzugsweise einen im Wesentlichen steigenden Verlauf aufweisen sollte.It should be mentioned that the riser should preferably have a substantially increasing course to improve the flow conditions and the cleaning.
Ein weiterer wesentlicher Punkt der vorliegenden Erfindung besteht darin, dass das Keg ein integriertes Reduzier- und/oder Rückschlagventil zum Anschluss eines CO2-Behälters aufweist, wobei dieses Ventil vorzugsweise so einstellbar bzw. voreingestellt ist, dass es einen Innendruck von 0,8 bis 1,2 bar im Fassinneren garantiert. An das Ventil kann dann ein externer CO2-Behälter angeschlossen werden oder aber - und das ist ein weiteres erfindungswesentliches Merkmal - das Keg weist einen integrierten CO2-Behälter auf, der eine ausreichende Menge an CO2 für das vollständige Entleeren des Kegs enthält. In diesem Fall benötigt der Benutzer des Kegs tatsächlich nichts anderes als einen einfachen Handzapfhahn, um in einfachster Weise ein den professionellen Gegebenheiten entsprechendes Bier zu zapfen, das weder eine übermäßige Schaumentwicklung aufweist, noch nach kürzeren bzw. längeren Standzeiten schal wird, da der nötige Druck zum Zapfen bzw. das Ausfüllen des sich im Fassinneren bildenden Hohlraums durch CO2 erfolgt, das in dem in das Keg integrierten CO2-Tank aufbewahrt wird. Gleichzeitig wird eine Verkeimung des Getränks durch Umgebungsluft vermieden und die Kegs bleiben innen feucht und sauber.Another essential point of the present invention is that the keg has an integrated reducing and / or non-return valve for connecting a CO 2 tank, this valve is preferably set or preset so that it has an internal pressure of 0.8 to 1.2 bar inside the barrel guaranteed. An external CO can be connected to the valve 2 container then be connected, or - and this is a further feature essential to the invention - the keg has an integrated CO 2 container for containing a sufficient amount of CO 2 for the complete emptying of the keg. In this case, the user of the keg actually needs nothing more than a simple tap to tap in the simplest way a beer that corresponds to the professional conditions, which neither has excessive foaming, nor scarf after shorter or longer periods, because the necessary pressure to tap or fill the cavity forming inside the cavity by CO 2 , which is stored in the integrated into the keg CO 2 tank. At the same time, contamination of the beverage by ambient air is avoided and the kegs remain moist and clean inside.
Besonders vorteilhaft ist es schließlich, wenn das CO2 in dem CO2-Behälter gasförmig ist. Hierdurch ist das Befüllen des einmal gebrauchten Kegs mit CO2 weitaus einfacher, als wenn dies im flüssigen Zustand vorliegen würde, denn dann müsste über eine aufwendige Volumenmessung die Füllmenge des CO2 kontrolliert werden. Flüssig wird CO2 beispielsweise bei 20 bar erst ab -10 °C, so dass das einzufüllende Volumen unter Berücksichtigung des Gewichts bei Beachtung von Druck und Temperatur errechnet werden muss. Im Gegensatz dazu ist es bei in gasförmigem Zustand vorliegenden CO2 in einfacher Weise möglich, den CO2-Tank solange zu befüllen, bis ein Druckausgleich mit dem CO2 der Zuführleitung vorliegt, wobei der CO2-Tank mit bis zu 60 bar befüllt werden kann.Finally, it is particularly advantageous if the CO 2 in the CO 2 container is gaseous. As a result, the filling of the once-used keg with CO 2 is much easier than if this would be in the liquid state, because then would have to be controlled by a costly volume measurement, the capacity of the CO 2 . Liquid becomes CO 2, for example, at 20 bar only from -10 ° C, so that the volume to be filled must be calculated taking into account the weight in consideration of pressure and temperature. In contrast, with CO 2 present in the gaseous state, it is easily possible to fill the CO 2 tank until a pressure equalization with the CO 2 of the feed line exists, wherein the CO 2 tank is filled with up to 60 bar can.
Ist das Reduzier- und/oder Rückschlagventil beim Zapfen im oberen Fasskörperbereich angeordnet, so hat dies den weiteren Effekt, dass das CO2 dort zugeführt wird, wo es gebraucht wird, nämlich oberhalb des Flüssigkeitsspiegels. Es muss also nicht erst die Flüssigkeit, also insbesondere das Bier, bei einem Zuführen von unten durchströmen und gegebenenfalls ein Schäumen verursachen, sondern füllt stattdessen einfach den oberen Bereich des Fassinneren aus, in dem sich kein Getränk (Bier) mehr befindet.If the reducing and / or non-return valve is arranged on the journal in the upper barrel body region, this has the further effect that the CO 2 is supplied to where it is needed, namely above the liquid level. So it must not first flow through the liquid, so in particular the beer at a feed from below and possibly cause foaming, but instead simply fills the upper area of the barrel inside, in which there is no more drink (beer).
Gleichfalls empfiehlt es sich hierbei auch, den integrierten CO2-Behälter im beim Zapfen oberen Fasskörperbereich anzuordnen, wobei zweckmäßigerweise der integrierte CO2-Behälter von einem oberen Kragenring oder einer Ummantelung umgeben und gegenüber der Umgebung geschützt ist.Likewise, it is also advisable in this case to arrange the integrated CO 2 container in the journal upper portion of the barrel, wherein expediently the integrated CO 2 container is surrounded by an upper collar ring or a sheath and protected from the environment.
Schließlich empfiehlt es sich, dass das Steigrohr seitlich neben dem Fitting in den Bodenbereich des Fasskörpers verläuft, wobei der "Bodenbereich" auf den Zustand beim Zapfen bezogen ist, also die Seite mit dem Fitting darstellt. D.h., es wird aufgrund des sich in Richtung des Fittings erstreckenden Steigrohrs nicht möglich sein, das Fass in der Orientierung zum Zapfen zu verwenden, in der das Fitting oben ist, da das Steigrohr im Fassinneren bis zur Fassoberseite verlaufen würde und sein Ende schon bald oberhalb des Flüssigkeitsspiegels läge.Finally, it is recommended that the riser runs laterally next to the fitting in the bottom area of the barrel body, wherein the "bottom area" is based on the state when tapping, so represents the side with the fitting. That is, due to the riser extending in the direction of the fitting, it will not be possible to use the barrel in the orientation of the spigot in which the fitting is at the top, since the riser would be up to the barrel top in the barrel interior and its end soon above the liquid level would be.
Insbesondere wenn man alle vorstehend aufgezählten Merkmale verwendet, erhält man ein Keg für den Hausgebrauch, das sich durch ausgezeichnete Bierqualität auch über einen längeren Zeitraum dadurch auszeichnet, dass nicht mit Luft, sondern mit CO2 gezapft wird. Das Integrieren des CO2-Tanks in das Keg ermöglicht es darüber hinaus, ohne zusätzliche Apparaturen, CO2-Flaschen bzw. -Patronen und dergleichen auszukommen und stattdessen ein Fass allein unter Verwendung eines herkömmlichen Handzapfhahns anzapfen und bis zum Schluss leeren zu können. Schließlich sorgt gasförmiges CO2 im CO2-Behälter für eine bessere Handhabbarkeit des Home Consumption Kegs in der Brauerei beim Befüllen des CO2-Tanks. Es sei noch darauf hingewiesen, dass alle hier aufgezählten Merkmale als eigenständige Erfindungen anzusehen sind, die ein gattungsgemäßes Keg in vorteilhafter Weise weiterbilden.In particular, using all the features listed above, you get a keg for household use, which is characterized by excellent beer quality even over a longer period in that is tapped not with air but with CO 2 . Integrating the CO 2 tank into the keg also makes it possible to manage without additional equipment, CO 2 bottles and the like, and instead to tap and empty a keg solely using a conventional manual tap. Finally, gaseous CO 2 in the CO 2 container ensures better handling of the home consumption keg in the brewery when filling the CO 2 tank. It should be pointed out that all features listed here are to be regarded as separate inventions, which further develop a generic keg in an advantageous manner.
Weitere Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnungen; hierbei zeigen
Figur 1- ein erfindungsgemäßes Home Consumption Keg in geschnittener Seitenansicht; und
Figur 2- die Draufsicht auf den CO2-Behälter des Home Consumption Kegs aus
Figur 1.
- FIG. 1
- an inventive Home Consumption Keg in a sectional side view; and
- FIG. 2
- the top view of the CO 2 container of the home consumption keg of Figure 1.
Das in Figur 1 dargestellte Home Consumption Keg 1 besteht aus einem aus zwei tiefgezogenen Halbschalen hergestellten Fasskörper 2, die an einer Schweißnaht 3 miteinander verschweißt sind. Das Keg weist ein an sich bekanntes Fitting 4 mit angeschlossenem Füllrohr 18 in dem in Figur 1 dargestellten oberen Bereich auf, der jedoch beim Zapfen den Bodenbereich des Kegs bildet. D.h., Figur 1 zeigt den Zustand zum Transportieren des Kegs, während für das Befüllen und Zapfen das Keg 1 "auf den Kopf gestellt werden muss", so dass sich dann das Fitting im Bodenbereich befindet. Auf der dem Fitting gegenüberliegenden Seite des Kegs, also in Figur 1 im unteren Bereich, ist ein Rückschlagventil 5 vorgesehen, durch welches das in einem CO2-Behälter 6 gelagerte gasförmige CO2 nach Druckreduzierung in einem Reduzierventil in das Fassinnere strömen kann.The
Der CO2-Behälter 6 ist aus Figur 2 in Draufsicht noch besser ersichtlich: Dort ist auch an einem Ende des C-förmig gebogenen CO2-Behälters das fest voreingestelltes Reduzierventil 7 zu erkennen und auf der anderen Seite des CO2-Behälters ein Verbindungsrohr 8, das den CO2-Behälter über einen Druckmessknopf 9 mit einer Zentraleinheit 10 und schließlich mit einem Hochdruckventil 11 zum Befüllen des CO2-Behälters verbindet.The CO 2 container 6 is shown in Figure 2 in plan view even better: There is also at one end of the C-shaped bent CO 2 tank the fixed
Im Gegensatz dazu ist das Reduzierventil 7 über ein Verbindungsrohr 12 mit dem Rückschlagventil 5 und damit dann mit dem Fassinneren in Verbindung.In contrast, the reducing
Der Fasskörper weist einen oberen Kragenring 13 und einen unteren Kragenring 14 auf, die dem Keg einen sicheren Stand verleihen bzw. es stapelbar machen und auch die CO2-Armatur sowie das Fitting gegen Einflüsse von außen schützen. Der in Figur 1 unten dargestellte Kragenring 14 ist beim Zapfen der obere Kragenring, während der Kragenring 13, der in Figur 1 oben dargestellt ist, beim Zapfen den unteren Kragenring darstellt. Der Kragenring 14 umgibt somit den CO2-Behälter und schützt ihn gegen Einflüsse von außen.The barrel body has an
Im beim Zapfen oberen Drittel des Fasskörpers, also in Figur 1 im unteren Drittel, ist ein Bayerischer Anstich 15 vorgesehen, der in die zylindrische Umfangswandung des Fasskörpers integriert ist und sich von dieser ausgehend radial nach innen erstreckt. In Verlängerung des bayerischen Anstichs 15 ist ein Steigrohr vorgesehen, das sich ausgehend von der radialen Erstreckung in Axialrichtung abgebogen bis zum Bodenbereich des Fasses erstreckt. Hierbei ist das Steigrohr 16 so beabstandet von der Axialachse des Fasses angeordnet, dass es den Bereich des Fittings 4 freilässt, um hierdurch insbesondere das Reinigen des Fassinneren durch die an sich vom Fitting ausgefüllte Öffnung 17 des Fasses nicht zu behindern.In the upper third of the barrel body, so in Figure 1 in the lower third, a
Wird nun das Fass zum Zapfen umgedreht, so befindet sich das freie Ende des Steigrohrs neben dem Fitting und dem daran angeschlossenen Füllrohr 18 fast ganz am Boden des Fasses und kann von dort das Bier aufnehmen und hierbei das Fass vollständig entleeren. Das Steigrohr besitzt einen inneren Durchmesser von lediglich ca. 2 mm, um einen möglichst großen Strömungswiderstand zu bewirken und hierdurch eine laminare Strömung des Bieres zu erzeugen, das zu einer äußerst geringen Schaumentwicklung selbst bei Benutzung simpler Zapfhähne führt.Now, if the barrel is turned over to tap, so is the free end of the riser next to the fitting and the connected
